The contents of heavy metal accumulated by air pollution in the cedar tree needles from the green area of Konya city centre were measured by chemical analyses. The needle samples were collected from two types of trees (about 10-15 and 20-25-years-old trees) from eight different pollution regions for two different sampling periods. Results of sulphur dioxide and particle matter analyses were used for measurement of air pollution effect on accumulation of heavy metals in the vegetation. Contents of heavy metals (Pb, Cu, Zn, Co, Cr, Cd and V) were determined for sampling periods, tree ages and sampling places. Results of the present study showed that accumulations of heavy metals in the old trees were generally higher than those of young trees. Similarly, heavy metal contents of needles collected in spring 2004 were higher than those of needles collected in autumn 2003. Accumulation of heavy metals via sulphur dioxide pollution and particle matter originated from usage of low quality fossil fuels, which might affect the living organisms in the city centre. On the other hand, Pb levels in the samples from Karatay Industry Park (3.53 ppm in 2004) showed that people are health living around the industry, and heavy traffic area is under risk. According to the other sampling areas, the chromium levels were also very high around the Chrome-Magnesite Factory Garden (87.15 ppm in 2004); it could be a toxic risk for people working around the factory. The heavy metal levels obtained from the other samples were not as high a risk level for the living organisms in the sampling areas. © 2005 Elsevier Ltd. All rights reserved.

Apart from water, living organisms need minerals, i.e. nutritional compounds and vitamins, to survive. Demand for minor minerals in the human body is quite low but most of them are essential as well. Heavy metals are components of mineral substances that are widely used for medical, agricultural, industrial, technological and domestic purposes and have effects on the environment. The present research was conducted by sowing 7 dry bean genotypes on 6 different dates for 2 years (2010 and 2012) in Konya, Turkey, to determine changes in heavy metal concentrations. According to the results, differences statistically significant at a 1% significance level were found for all the factors and their interactions except for the year factor. Mean concentrations of the analysed minerals ranged as follows (in mg kg-1): 0.00-0.06 for Cd, 0.00-0.84 for Co, 0.36-10.47 for Cr, 1.06-14.17 for Cu, 6.81-59.71 for Fe, 1.65-12.31 for Ni, 0.00-0.44 for Pb and 2.31-26.27 for Zn. In summary, the content of Co, Cu, Ni and Zn showed a decrease in beans sown late, while Cr and Fe presented a decreasing tendency in general. Additionally, the content of Cd and Pb in beans sown on 15th May at the latest varied depending on the sowing dates. Consequently, delayed sowing of bean resulted in a significant decrease in the heavy metal content of dry bean seeds. Further studies into the nutritional quality and agronomic characteristics of plants are needed, including such aspects as well-balanced yield and quality traits, in order to ensure sustainable functional food production and sustainable agricultural systems.
